Abstract

Innovative therapies are urgently needed to combat cancer. Thermal ablation of tumor cells is a promising minimally invasive treatment option. Infrared light can penetrate human tissues and reach superficial malignancies. MXenes are a class of 2D materials that consist of carbides/nitrides of transition metals. The transverse surface plasmons of MXenes allow for efficient light absorption and light-to-heat conversion, making MXenes promising agents for photothermal therapy (PTT). To date, near-infrared (NIR) light lasers have been used in PTT studies explicitly in a continuous mode. We hypothesized that pulsed NIR lasers have certain advantages for the development of tailored PTT treatment targeting tumor cells. The pulsed lasers offer a wide range of controllable parameters, such as power density, duration of pulses, pulse frequency, and so on. Consequently, they can lower the total energy applied and enable the ablation of tumor cells while sparing adjacent healthy tissues.

Development of tailored MXene PTT treatment targeting tumor cells. We demonstrate both low toxicity and good biocompatibility of this MXene in vitro, as well as a favorable safety profile based on the experiments in vivo.

We show for the first time that a pulsed 1064 nm laser could be employed for selective ablation of cells loaded with Ti3C2Tx MXene. We demonstrate both low toxicity and good biocompatibility of this MXene in vitro, as well as a favorable safety profile based on the experiments in vivo. Furthermore, we analyze the interaction of MXene with cells in several cell lines and discuss possible artifacts of commonly used cellular metabolic assays in experiments with MXenes. Overall, these studies provide a basis for the development of efficient and safe protocols for minimally invasive therapies for certain tumors.

Keywords: MXene, photothermal therapy, cancer cell, pulsed near-infrared laser, in vivo, safety

Delivering help to Ukraine from the USA, Europe, and the rest of the world!

3.jpg - 197.81 KbOur organization in Kyiv, Materials Research Center, is well aware of the needs in Ukraine now. Together with our partners, fellow Ukrainian scientists, we have organized a warehouse in Lviv, where we collect cargos and distribute them throughout Ukraine, with detailed reports confirming the delivery to the final destination, including photos of the transfer. We have transportation that can pick cargo in Poland and deliver it through a green corridor for humanitarian cargos at the Polish-Ukrainian border. 
We are ready to respond promptly, as required by the situation in Ukraine. If there are individuals, foundations or volunteer organizations willing to send help to Ukraine from Europe or the United States, we are ready to accept it in our warehouses, make collection or individual parties according to your request and pass them on to those in need. All humanitarian aid, first aid, and protective gear will be delivered to the final destination.
